SYMPTOMS

If you have a secure socket layer (SSL) site on an Application Center 2000 cluster that requires high rates of forwarding by way of the Application Center 2000 Request forwarding filter, the Lsass.exe file may expand to take all available memory. Note that INETINFO also shows high memory and handles counts in this case.

CAUSE

The Lsass.exe cache is attempting to grow beyond available memory.

RESOLUTION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Limit the maximum size of the Lsass.exe cache by way of registry settings, as follows:
  1. Start Registry Editor (Regedt32.exe).
  2. Locate the following key in the registry:

    HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/SecurityProviders/SCHANNEL

  3. On the Edit menu, click Add Value, and then add the following registry value:

    Value Name: MaximumCacheSize
    Data Type: REG_DWORD
    Radix: Hexadecimal
    Value: 000003e8

  4. On the Edit menu, click Add Value, and then add the following registry value:

    Value Name: MinimumCacheSize
    Data Type: REG_DWORD
    Radix: Hexadecimal
    Value: 000003e8

  5. Quit Registry Editor.
You must restart your system for this change to take place.
